I am going to add in top100golfcourses.com because I think their list is as strong and legitimate as the other publications.
Isn't the baseline for the top100 website's rankings, in fact, a composite of other rankings like you have already been doing?
It's never been clear to me how much weight their panelists' votes actually have on their list . . . if any.
Maybe someone in the know (calling David Davis) can jump in but I thought Top 100 was a panel and there was no formula involving aggregation of other publications involved. Certainly their regional lists would imply not.
